IMPROVEMENT in GANG-PLOWS.

Specification forming part of Letters Patent No. 184,665, dated November21, 1876; application filed August 26, 1876.

To all whom it may concern:

Be it known that 1, WILLIAM M. RICHARD- SON, of Roscoe, in the county ofWinnebago and State of Illinois, have invented a new and valuableImprovement in Gang-Flows; and I do hereby declare that the following isa full, clear, and exact description of the construction and operationof the same, reference being had to the annexed drawings, making a partof this specification, and to the letters and figures of referencemarked thereon.

Figure l of the drawings is a representation of plan views of mygang-plow, and Fig. 2 is a side view of the same.

This invention relates to gang-plows; and the nature of said inventionconsists in certain improvements therein, as will be hereinafter setforth and claimed.

In the annexed drawings, A'A indicate the two longitudinal bars of mymetal beam or frame, which converge in front at a, where they aresecurely bolted together with a wooden attaching-block, B, between them.Bar A curves outward and backward from neck a, and then runs straightback to its rear end a which curves downward. Bar A runs straight backfor some distance from neck a, then curves outward, and then runsstraight backward again to its rear end 60 which curves downward likethe rear end a of bar A. Bar A is somewhat shorter than bar A, so thatthe curved end a is obliquely in advance of the curved end a Bars A andA are connected near their rear ends by an oblique metal cross-piece, G,and also near their middle parts by a cross-piece, D, at right angles tothe line of draft. Clip 111' embraces bars A and A just outside ofcross-piece D, and prevents them from straining apart.

The construction above described'produces, as a whole, a frame orcompound plow-beam,

which has, first, a narrow neck, then a broader though still somewhatnarrow portion to the rear of said neck, and mainly on one side of itscentral longitudinal line, and, finally, a broad rear portion, whichlies mainly on the other side of said central longitudinal line.

F F designate the standards of the plows, and each of said standards isprovided with a horizontal longitudinal arm, f, for attaching the sameto the inside of beam above described, and also with a brace-rod,fextending from the end of arm f to the main part of the standard. .Eachof said standards is also bifurcated at the bottom so as to present avertical extension, f and an oblique forward and downward extension, fThese extensions or feet f f are secured in each case to the inside ofthe land-side G of one of the plows. Said plows are constructed alike,and after the usual manner, H H being the moldboards, I I the shares,and J J curved bracerods, connecting in each case the rear of landside Gwith the rear of share I and mold-board H. Standard F is secured tolongitudinal arm A of the above-described compound plowbeam at a pointsomewhat more to the rear than that at which standard F is attached tolongitudinal bar or arm A of said beam, so that one of said plows isobliquely in the rear of the other. Their furrows will, however, lieparallel. K K designate oblique brace-rods, each of which extends fromthe curved end of one of the aforesaid beam arms or bars A or A, as thecase may be, to the obliquely-downward-projecting extension or foot f ofthe standard F or F, secured to said bar or arm. The lower end ofbrace-rod K is rigidly secured by bolting or otherwise to the saidoblique extension f The upper end of said brace-rod is screw threaded,and passes through a perforation in the curved end a or a of bar A or A,as the case may be, and is secured by nuts above and below saidperforation, so as to be adjustable lengthwise.

By this construction the said brace-rod K may be used with plows ofdifferent sizes, and may also be so adjusted as to compensate for anycontractions or expansions produced by changes of temperature, while itfirmly braces the plow and standard. Rods K K are exactly alike inconstruction, attachment, and

use.

The front block B is vertically perforated at b, or otherwise adapted tobe fastened to a plow attachment of any ordinary construction. Exceptingsaid block, all the parts described in this specification are preferablymade of metal, though some of them may be-ot' wood or other suitablematerials.

The form and arrangement of the beam,

standards, braces, 850., may be modified in various ways withoutdeparting from the spirit of my invention. i it a What I claim as new,and desire to secure by Letters Patent, is-

The gang-plow herein described, consisting of the bent longitudinal barsA A, connected by the bars 0 D, all made in one piece, and standards FF, having upper extensions f and lower extensions 1) bolted to the landsideslG G of plows. substantially as described, and for the purpose setforth.

i. Intestimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses. y I r WILLIAM RICHARDSON.
